- Cross-Dressing Voices: Ken is voiced by Angélica Santos in the flash episodes at the start of Revolution.
- Relationship Voice Actor: Tati and Ken's voice actresses are also the official voice actresses for Monica and Jimmy Five, respectively. It gets funny when you compare the relationships between both pairs of characters.
- Lisa and Luke's VA's are mother and son. This could be considered heartwarming or creepy.
- Technology Marches On / Unintentional Period Piece: Some of the computer/cable TV references in the dialogue look incredibly dated when they're read again a decade later (like in Zero, where a girl smitten with Luke asks for his ICQ number as he saves her, or when Maya breaks into the Combo Base and is surprised to see they have DirecTV, which stopped operating in Brazil in 2007, being replaced by SKY).
